I'm not sure if people know, but everything is geared towards "being married".  Bahhaha, bhaha...sheep.
Imagine how many industries would be crippled without people getting hitched.
I also find it funny how the same service, somehow triples if it's a marriage.
My favorite thing about marriage is when a couple has to tell everyone...I'm getting divorced...guess he wasn't the one. 

There is no commitment in marriage.  There's more obligation in signing a one year lease on an apartment.
Much like popping a cherry, I think if you get married once, then divorced...you can marry no more.  Clearly you can't make it work.  That's the risk you take.  One chance fuckstick.
